Investigation of the photoluminescence properties of composite optical resins containing high lanthanide content

► Novel composite optical resins with high lanthanide content have been synthesized. ► The Eu(DBM)3·H2O nanocrystals were within the range of 30 to 300 nm. ► Fluorescent resins with high lanthanide content (50 wt%) were obtained. ► Resins exhibit intense emission of lanthanide and longer fluorescence lifetimes. ► Variety properties of Eu(DBM)3·H2O nanocrystals were characterized.
